-LRB- CNN -RRB- -- `` Losers '' or victims of a framing ?

With officials seeking possible motives for the men who stand accused of the Boston marathon bombings , a picture is emerging from those who should have known Tamerlan Tsarnaev , 26 , and his brother , 19-year-old Dzhokar , best -- their family members .

As a nation grieves over the three people killed in the bombings , the scores injured and a police officer who lost his life during the search for suspects , members of the Tsarnaev family have gone on record to express their feelings about the possible guilt or innocence of the pair . This is what they had to say :

The mother

Zubeidat Tsarnaeva says it is `` impossible , impossible '' for her sons to have committed such a crime .

Speaking from the Russian region of Dagestan , she expressed support for her children and said she believes they have been the victims of a setup .

`` You tell me , my son never would keep it in secret , '' she said . '' ... If there is anyone who would be knowing it would be me . -LRB- Tamerlan -RRB- never would hide it from me . ''

The family matriarch also said no one talked about terrorism in their household . Her oldest son had had contact with the FBI before , she said .

`` They knew what my son was doing , what actions and what sites -LRB- on -RRB- the Internet he was going , '' she said . `` How could this happen ? ''

Boston suspects : Immigrant dream to American nightmare

The father

`` Someone framed them , '' Anzor Tsarnaev said while the manhunt was being conducted . `` I do n't know who exactly did it , but someone did . ''

He said he had spoken with his sons on Thursday and they told him , `` Everything is good , Daddy . Everything is very good . ''

After being told by ABC News on Friday that his youngest son had been captured alive , the elder Tsarnaev reportedly began to weep and had this message for his child : `` Tell police everything . Everything . Just be honest . ''

On Saturday , he told CNN 's Nick Paton Walsh that he planned to travel to the United States .

`` My kids never did anything -- that 's it , '' he said .

The sister

Alina Tsarnaeva told The -LRB- Newark , New Jersey -RRB- Star-Ledger that she had not seen her brothers `` in a long time '' but spoke lovingly of Tamerlan .

`` He was a great person , '' she said . `` I thought I knew him . I never would have expected that from him . He is a kind and loving man . The cops took his life away just the same way he took others ' lives away , if that 's even true . At the end of the day , no one knows the truth . ''

Analysis : Older suspect grew increasingly religious

An uncle

After the death of Tamerlan and as authorities continued to hunt his younger brother , their uncle Ruslan Tsarni spoke passionately at a news conference Friday outside his Montgomery County , Maryland , home .

`` Being losers , hatred to those who were able to settle themselves -- these are the only reasons I can imagine , '' Tsarni said when asked to speculate on a possible motive . `` Anything else , anything else to do with religion , with Islam , is a fraud , is a fake . ''

The uncle admonished the pair for putting `` a shame on our entire family -- the Tsarnaev family -- and you put a shame on the entire Chechen ethnicity . ''

By Saturday , he appeared to have a bit of a change of heart , telling CNN 's Shannon Travis that he was angry when he spoke Friday . He said he was still in a `` state of shock '' but expressed happiness that his younger nephew had been captured alive and said his elder nephew had fallen prey to outside influences , according to a family acquaintance .

'' -LRB- The acquaintance -RRB- said there is someone who brainwashed him , some new convert to Islam , '' Tsarni said . `` I would like to stress -LRB- the acquaintance was -RRB- of Armenian descent . ''

An unidentified relative in Dagestan told ABC News that Tamerlan had worried family members a year ago during a trip there and had been asked to leave an uncle 's home because of his `` increasingly extremist views . ''

An aunt

Tsarni was not the only one who passionately spoke about the Tsarnaev brothers .

Maret Tsarnaev said she believed the picture of the bombing suspects that purportedly helped lead authorities to her nephews was `` staged . ''

`` If somebody wants to convince me , show me evidence , '' she said , telling reporters Friday she is studying to become a lawyer . `` Evidence ! Evidence ! ''

At times seeming almost combative during a press conference , she said it would take much more than photos to convince her that her nephews had committed such a crime . `` What I 'm saying is , why FBI does not give me more ? ''

The wife

Katherine Russell is the 24-year-old wife of Tamerlan Tsarnaev and mother of their 3-year-old daughter , Zahara . Approached by Britain 's Daily Mail at her family 's home in New Hampshire , she declined to comment . Her family released the following statement Friday :

`` Our daughter has lost her husband today , the father of her child . We can not begin to comprehend how this horrible tragedy occurred . In the aftermath of the Patriots ' Day horror , we know that we never really knew Tamerlane Tsarnaev . Our hearts are sickened by the knowledge of the horror he has inflicted . Please respect our family 's privacy in this difficult time . ''
